BRITISH MOTHS 







Species 7- — Geometra lunaria''. — (Plate LIX., Figs. 15, 16.) — This species varies from \-i^ to If iDch in 

 the expanse of the fore wings, which are of an ashy-red colour, but slightly atomose, with two rather slightly 

 marked strigee (between which is a white lunule) the first incurved before the middle of the wing, the second 

 straight a little beyond the middle, but slightly beyond the white lunule ; the apex with a semi-lunule of red- 

 brown ; the hind wings with a white lunule, edged with brown, beyond which is a slender brown striwa. The 

 female is paler and more atomose. The caterpillar is brown, varied with dark markings and patches of reddish- 

 brown, and with conical tubercles on the back. It feeds on the whitethorn, and the moth appears in June, 

 and is widely dispersed, but rather rare.

Species 8. — Geometra delunaria ' — (Plate LIX., Fig. 17) — -measures 1^ inch in the expansion of the 

 fore wings, which are grayish-white, scarcely atomose, and with an oblique striga towards the middle of the 

 wing, of a brown colour, and extending across the hind wings ; the fore wings, moreover, with another incurved 

 striga in the middle, and the hind wings with two adjoining, to the outer of which, is a diaphanous but ; rather 

 obsolete lunule. The hind wings are less denticulated than in the last species, although Mr. Stephens suspects 

 it may prove to be but a variety of it. Boisduval, however, affirms its distinction. " Taken at Birch Wood, 

 in July," according to Mr. Stephens.

Species 9. — Geometra illustraria". — (Plate LIX., fig. 18). — This species measures from If to 2 inches 

 in expanse, all the wings being varied with dark brown and ashy from the base to the middle, with a white 

 lunule, an incurved dark striga near the base, the apical portion purplish-buff, with a bright red apical lunar 

 mark, and a brown apical cloud behind ; hind wings similar, but rounded, and with a brown dot towards the 

 apical margin, the middle of the wing marked also with a white lunule. The Caterpillar is reddish or brown, 

 with white and dark brown spots and stripes. It feeds on oak and other trees, and the moth appears in May 

 and June, but is a rare species ; found in the woods of Kent, the New Forest, Devonshire, &c.

Species 10. — Geometra sublunaria". — This species is closely allied to the last, but is smaller (measuring 

 from li to If inch in expanse) with the fascia beyond the central limule slightly flexuous, and extending nearly 

 to the anal angle ; the hind wings reddish, with a brown fascia extending from the anal margin, and enclosing 

 the central whitish lunule : these wings are very much more strongly scalloped along the margin than in the 

 last species. Rare. Derbyshire.

PERICALLIA, Stephens. ENNOMOS, p. Treitschke. 

 The type of this genus is closely allied to the last, but the antennae are bipectinated in both sexes, although 

 less strongly in the females than in the males ; the fore wings are not elevated in repose, and are not strongly 

 lobed as in Geometra ; the palpi are rather short, the larva 10-footed, slender in front, with the fourth segment 

 tuberculated, and two long recurved hooks on the eighth segment ; the chrysalis is short and thick, and supported 

 by a light web amongst leaves.
